of the same'being shown in the patent of Charles Swinscoe, No. 712,212, dated Oct.j28, 1902.

- heretofore, wire connecters have been employed for connecting the sections or panels of belts of this type and in some instances bar connecters have also been employed, particularly when such sections or panels comprise individual warrant or' require.

helically twisted wires having right-hand and left-hand convolutions; one notable example being the structure illustrated in the application of volutionswith consequent narrowing of the fabric, takes place under the traction applied to the belt in pulling or passing it around driving pulleys or other pull-transmitting means.

The principal object of my invention is to permanently secure connecter members to the helically twisted wires at various points through out the length of the belt whereby I am enabled to provide means that will prevent lateral displacement of the wires and avoid the narrowing of the fabric making up the belt.

In Figs. 1, 2 and 3.1 have shown a series of helically twisted wires making up a belt of this type; a sufficient number of such wires being shown to indicate their character, and they may beemployed in any desired number to form a complete belt of any desired length. For the purpose of preventing lateral displacement of the wires making up such belt,'I introduce flat bars therein. at intervals throughout the length of the same and weld the convolutions of such wires, or one of them, to such bar. In Figs. 1, 2 and 3, 1, 1, represents the helically twisted wires having convolutions providing the upper and under (or lower) ribs 1 and 1 In this type of belt, the respective ribs extend in the same direction. Within the space between the upper and under (or lower) ribs of certain of these helically twisted Wires I introduce a flat bar, such as indicated at 2, which is preferably of a length, crosswise of the belt, the same as the helically twisted wires, and by preference this connecter bar occupies the space between the convolutions of the adjacent wires, as clearly indicated in Figs. 1 and 2. This bar is secured in place by welding the convolutions of the'adjacent wires thereto, as indicated at 3, or by welding'the upper and under (or lower) ribs of the convolutions of the helically twisted wire through which such connecter bar passes, as indicated at 3 These connecter bars may be employed at suitable intervals throughout the length of the belt; being provided in such number as conditions of use of any particular belt may It will be understood that while I have shown this connecter bar 2 as associated with helically twisted wires of the character illustrated; that is to say, wires whose upper ribs extend in the direction indicated from upper left to lower right, I may employ connecter bars of such type with belts made up of helically twisted wires whose upper ribs extend in what maybe termed an opposite direction; that is to say, from upper right to lower left, without departing from my invention. In practice these wires are termed right and left and the twist of the wires shown in Figs. 1, 2 and 3, is a right-hand twist.

In Figs. 4 and 5 I have shown a connecter bar disposed between two sections or panels of wire fabric, in this instance sections of right-hand twisted wires, indicated generally at A. The connecter bar 22, shown in Figs. 4 and 5, is of channel-shape or contour in cross-section; comprising a web indicated at a providing a fiat surface which will lie in the plane of the upper ribs 1 of the wire fabric so as to form a substantially plane surface continuous therewith, and edge ribs or flanges b, which may extend to the plane of the under (or lower) ribs 1 of the helically twisted wires. The convolutions of the helically twisted wires on opposite sides of this channel-shape connecting member are welded thereto as indicated at 33.

In Figs. 6 and '7 I have shown sections or panels of wire fabric made up of helically twisted wires in which the wires 1, of one section or panel, indicated at A; that illustrated in the drawings as disposed above the connecter member, may have their upper ribs la lying in one position; being made of right-hand twisted wires, for instance,

while the section or panel of fabric indicated at B in such view as disposed below the connecter member and made up of helically twistedwires 11, have their upper ribs 11 lying in the opposite direction; being made up of left-hand twisted wires, for instance. In other words, such belt is made of sections or panels of right-hand twisted wires alternated with sections or panels of lefthand twisted wires. These sections or panelsi may be joined by a connecter member 22 ofchannel section, the same as that illustrated in Figs, 4 and 5, and the convolutions of the respective helically twisted wires of the respective sections or panels may be welded to such connecter bar at 33.

In Figs. 8, 9, 10, 11 and 12, I have shown crosssectional views similar to Fig. '7, illustrating connecter members of different cross-sectional contours.

Fig. 8 shows a connecter member or bar 2*, of the type illustrated in Figs. 1, 2 and 3.

Fig. 9 shows a connecter bar or member 22 rectangular in cross-section.

Fig. 10 shows a connecter. bar or member 22*, oval in cross-section.

Fig. 11 shows a. hollow connecter member 229, which may be oval in cross-section, and Fig. 12, shows a connecter bar or member 22 substantially hexagonal in cross-section.

In all instances the connecter members preferably occupy a space equaling the space between the convolutions of the helically twisted wires so that the pitch of the chain, so to speak, is not altered by the presence of the connecter members; hence a belt provided with connecter members such as I have devised may be passed over toothed driving members, if desired, with the assurance that the teeth of the same will mesh properly with the spaces provided by the openings between adjacent wires making up the fabric of the belt. If, however, this spacing of the wires making up the belt is not essential in the operation of use of the same, the connecter 130 members'may be of regular contour and equal dimensions in all directions in cross-section; that is to say, square, round, hexagonal, or of other polygonal shape, or the like, as may be desired. And in lieu of hollow connecter members of oval 135 contour such as illustrated at 22 in Fig. 11, I may employ round tubes to the surface of which the convolutions of the helically twisted wire strands may be welded.

It is also within the scope of my invention to 140 provide the connecter members with flanges or webs projecting from the same and above or beyond the surface of the belt and at any desired curve or angle thereto to serve as conveyer flights. In this connection I have shown in Fig. 145 13 a connecter member 22 having a flange 'or web 5 which may be integral with the same, and in Fig. 14 I have shown a connecter member 22 having a flange or web 5 of curved form which may be integral therewith. It will be under- 150 stood, of course, that these webs or flanges may be separate members and attachable to any of the forms of connecter members shown.

The art of making belts of these helically twisted wire strands is too well known to re-' quire elaborate description. In carrying my invention into eiiect I may weave sections of the fabric, or in the case of the arrangement shown in Figs. 1, 2 and 3, the fabric may be woven in any lengths, and the connecter members applied as desired; being placed within the convolutions of individual wires which may be welded thereto as indicated. The number of these connecter members or stretcher bars may be such as the use to which the belt is to be put may require.

In the case of the connecter members which are interspacedbetween sections or panels of the wire fabric, which sections may be made up of wires having their convolutions extending in the same direction, or sections or panels whereinthe wires of one have convolutions extending in one direction--right-hand,' for instanceand the other section or panel has wires whose convolutions extend in the opposite direction-lefthand, for instance-the end wires of the respective sections are so placed that the convolutions of the samethroughout their length abut and touch the sides or edges of such interspaced connecter members, and then by means of suitable welding appar'atuselectric arc-welding for in stance, the touching or abutting portions of such convolutions are welded to the sides or edges of the connecter members. And this manner of permanently securing the connecter members to. the'wires of the panels or section of wire fabric making upv the belts may be carried out with all forms of connecter bars shown.- It will be understood, of course, that I am not limited to the forms of connecter bars shown, and that any form of bar which may be employed in the manner illustrated and to which the convolutions of the helically twisted wires may be welded on I oth rwise permanently secured, is within the scope of my invention. 1

At the same time, other means of securing the helically twisted wires to the connecter bars or members may be .employed, and it is within the scope of my invention to employ connecter members to which single helically twisted or coiled wires are attached at'the opposite sides or edges thereof; either pairs of wires with right-hand convolutions, pairs of wires with left-hand convolutions or a wire with a right-hand convolution on one sideor edge of such connecter memher, and a wire of left-hand convolutions on'the opposite side or edge of such connecter member, and to apply such connecter member to the wire twisting or coiling machine as the wires are being helically coiled or twisted to form the fabric, so that at the required spacings these permanently attached connecter members may be associated with the belt fabric made up of the several interlaced helically twisted wires. When so arranged or when arranged in any manner, the ends of the connecter members may be perwires of the fabric, so that accidental removal ofthe connecter members is impossible. It will are necessary, and that fresh wires may be woven in. at any time, as well as fresh connecter members "applied.
